Definition

Entropic gravity is the attributed program in which gravitational behavior emerges from entropy and information change rather than being introduced as a primitive force. The corpus traces it through Verlinde and presents Schlatter and Kastner’s transactional account as a proposed microscopic grounding. This remains a speculative program, especially where information gain is identified with thermodynamic entropy change, rather than an established replacement for general relativity.

Explanation

In the transactional version, localization of an emission reduces spatial uncertainty and supplies information. The program connects that change to compensating entropy effects and gravity. The source expressly marks the passage from Shannon information to thermodynamic entropy as debated, so a common mathematical vocabulary does not by itself establish a physical identity between the two quantities.

RB2 introduces gravity conventionally as force or spacetime curvature before describing the Schlatter–Kastner alternative. It states their account as a proposal tied to electromagnetic transactions and localization. The proposal must remain attributed to these authors rather than silently becoming a consensus derivation of every gravitational effect from ordinary information processing.

The holographic-screen reinterpretation and the stronger mass-substratum account belong to the same program but have their own claims. The books repeatedly say the later philosophical argument does not depend on this conjectural frontier. No external observational fit, experimental discriminator or complete quantitative derivation has been newly verified by this local assessment.
